Searching via Disconnect should show no XSS false positive warnings
https://blog.torproject.org/blog/tor-browser-452-released#comment-95374 describes a way to trigger NoScript's XSS warning reliably:
Whenever I search a term using the right click->"Search for *", it goes to the disconnect search page and NoScript gives error "NoScript filtered a potential cross-site scripting (XSS) attempt from [chrome]. Technical details have been logged ..."This does not happen with other search engines, like the one Google provides.
